Description

Technical Field

[0001] The invention relates to the field of magnetic heads, and in particular to a magnetic head shell polishing device. Background Art

[0002] The magnetic head refers to the component that reads data on the magnetic medium through the magnetic principle. Common magnetic heads include hard disk heads, tape recorder heads, etc. The existing currency detector magnetic head housing has an opening on one side, which is used to fix the original part of the currency detector magnetic head. The other side of the shielding cover is provided with a through hole, through which the banknote signal is collected.

[0003] When producing magnetic heads, the magnetic head shell needs to be polished. Patent application number: 201721782236.0 discloses a polishing device for producing magnetic heads. After the magnetic heads are produced, the magnetic heads to be polished are placed between the upper fixed block and the lower fixed block, and locked by a locking mechanism. The rotating rod is rotated, and the movement of the movable box is driven by the rotation of the threaded rod, thereby realizing the movement of the grinding disc, and then the magnetic heads are polished by the grinding disc. However, this type of polishing device is inefficient in polishing magnetic heads. The magnetic heads need to be fixed before polishing, and the magnetic heads need to be removed after polishing before the next polishing can be performed, and the polishing efficiency is low.

[0004] The present invention is proposed in view of the deficiencies in the prior art. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a magnetic head shell grinding device.

[0006] The present invention can be implemented by the following technical solutions: The invention discloses a magnetic head shell grinding device, comprising a frame, a rotating motor is fixed on the frame, a turntable is fixed on the output end of the rotating motor, a plurality of rotating shafts rotatably connected to the turntable are evenly arranged on the turntable, through holes are arranged on the turntable at the bottom of the rotating shaft, a positioning block is also fixed on the bottom of the rotating shaft, a positioning plate is fixed on the positioning block, a torsion spring is also fixed between the positioning block and the turntable, a fixing block is fixed on the top of the rotating shaft, a slide plate is also arranged above the turntable, a plurality of sliding rods are also fixed on the frame above the turntable, sliding tubes are arranged on the slide plate at positions corresponding to the sliding rods, the sliding rods pass through the sliding tubes and are slidably connected to the sliding tubes, grinding blocks are also symmetrically fixed on both sides below the slide plate, the slide plate is driven by the grinding motor to move on the sliding rod, a limiting plate used in conjunction with the positioning plate is also fixed on the frame on one side of the turntable, two polishing motors are also fixed on the frame at the position of the limiting plate, the two polishing motors are symmetrically arranged on the frames on both sides of the turntable, and grinding wheels are fixed on the output ends of the polishing motors. Fix the magnetic head shell to be polished with the fixed block, insert the fixed block into the shell and fix the shell on the fixed block. After the shell is fixed, the rotating motor drives the turntable to rotate a certain angle, and the shell rotates with the turntable to between the two polishing blocks. The polishing motor drives the rotating block to rotate. When the rotating block rotates, the pull rod rotates with the rotating block. The pull rod pushes the slide plate to move back and forth on the slide bar through the push plate, so that the two sides of the shell can be polished, and the shell is fixed on the next fixed block again. The rotating motor drives the turntable to rotate again. When the turntable rotates, the positioning plates at the positions of the polished shells on both sides contact the limit plates and push the rotating shaft to rotate. The outer shell passes through two grinding wheels after the high-speed rotating grinding wheel contacts with the other two sides of the outer shell, and the outer shell is polished. The polished outer shell rotates with the turntable. After the positioning plate and the limit plate are separated, the rotating shaft rotates back to the initial state due to the torsion spring. After the outer shell reaches the specified position, the polished outer shell is removed and the outer shell to be polished is placed again. The operation is cyclic. The device can polish the four sides of the outer shell and place the magnetic head outer shells to be polished one by one while polishing, which greatly improves the polishing efficiency of the magnetic head.

[0007] Preferably, avoidance holes are provided on the turntable on one side of the positioning plate.

[0008] Preferably, the through holes are each provided with a positioning rod used in conjunction with the positioning plate. By providing the positioning rod to block the positioning plate, the housing can be ensured to pass between the two grinding blocks.
